FDA Grants $4.3 Million Small Business Waiver, Enabling Focus on Commercialization Preparations

Company On Track to Initiate NDA Submission by the End of this Month

PETACH TIKVA, Israel, March 17, 2026 (GLOBE NEWSWIRE) -- PolyPid Ltd. (Nasdaq: PYPD) ("PolyPid" or the "Company"), an innovative biopharmaceutical company dedicated to improving patient outcomes by elevating treatment effectiveness, right where care begins, today announced that the U.S. Food and Drug Administration (FDA) has granted a small business waiver of the Prescription Drug User Fee Act (PDUFA) fee of approximately $4.3 million for the New Drug Application (NDA) for D-PLEX₁₀₀, the Company's lead product candidate for the prevention of surgical site infections (SSIs) in abdominal colorectal surgeries.

This meaningful waiver advances PolyPid toward its upcoming NDA submission initiation and enables the Company to focus its resources on commercialization preparations, following the successful Phase 3 SHIELD II trial which demonstrated a 60% (p=0.0013) relative risk reduction in surgical site infections and met its primary and all key secondary endpoints. The Company remains on track to submit the first sections of its rolling NDA by the end of this month, following positive feedback from the FDA during the pre-NDA meeting communication completed in December 2025.

"We are pleased to receive this PDUFA fee waiver days before our planned NDA submission," said Dikla Czaczkes Akselbrad, Chief Executive Officer of PolyPid. "Following our landmark Phase 3 SHIELD II results and productive engagement with the FDA on our rolling NDA review approach, we continue to make significant progress toward bringing D-PLEX₁₀₀ to market. With D-PLEX₁₀₀ seeking to address a significant unmet need in a major surgical infection prevention market, we are in advanced stages of commercial partnership discussions for the U.S. market while preparing for what we expect to be a transformative year for PolyPid."

About D-PLEX₁₀₀
D-PLEX₁₀₀, PolyPid’s lead product candidate, is designed to provide local prolonged and controlled anti-bacterial activity directly at the surgical site to prevent surgical site infections (“SSIs”). Following the administration of D-PLEX₁₀₀ into the surgical site, PolyPid’s delivery technology, Kynatrix, pairs with Active Pharmaceutical Ingredients, enabling a prolonged and continuous release of the broad-spectrum antibiotic doxycycline, resulting in a high local concentration of the drug for a period of 30 days for the prevention of SSIs, with additional potential to prevent SSIs caused by antibiotic-resistant bacteria at the surgical site. D-PLEX₁₀₀ recently demonstrated positive results in the Phase 3 SHIELD II trial, achieving a statistically significant 60% (p= 0.0013) relative risk reduction in SSI incidence following abdominal colorectal surgery with large incisions. D-PLEX₁₀₀ received Breakthrough Therapy Designation from the U.S. Food and Drug Administration for the prevention of SSIs in patients undergoing elective colorectal surgery.
